If their durability has anything to do with their build quality, they should be very durable. The one's I've handled exemplify this. I bought a 10x42HD bino to use this past season. It's is exceptional in every way, as well built as anything I've ever handled or owned. Not to sound like a broken record, but one of the main things I like about them is that they make everything in house, including glass grinding, polishing, coating. The only other manufacturer who does this is S&B, and their pricing shows it.
If I'm not mistaken (don't hold me to this yet), the only difference between the R1 and R2, besides configurations and maybe some reticles, is that the R2's are all 2nd focal plane, and the R1 may be 1st or 2nd depending on the model.
